To all whom, it may concern: i Be ittknown that I, ALBERT H. LEW-1s, a

citizen of the United States, residing at,

New (Jomerstown, in the county of Tusca- 5 raWas-and State ofOhio, haveinvented new adjacent its upper end,

and useful Improvements in Collapsible -ore-l3ars, of which thefollowing is a speciflcation.

My present invention has to do with col, lapsible core bars, such as areused in metal founding; and it contemplates the provision of a sectionalandccllapsible core bar, I embodying peculiar and advantageous means fordetachably securing the sections against movement with respect to eachother, and for releasing the sections at the proper time for suchmovement, so as to facilitate the withdrawal of the core bar.

With the :t'oregoing in mind, the invention in all of its details willbe any understood from the following description and claims when thesame are read'in-connection with the drawings, accompanying and formingpart of this specification, in which:

Figure 1 is a View, partly in elevation and partly insection, showing mynovel core bar or print with the body sections locked for use. Fig. 2 isa similar View shmving the core bar or print in a collapsed state. IFig.3 is an enlarged detail section illustrative of the resilientlatches and the parts adjacent thereto. Figs. 4 and 5 are sections takenon the lines H and .5-5, respectively, of Fig. 1.

Similar letters designate parts in all of the views of. referring towhich: I

A A are the downwardlytapered metallic sections, and BB are theupwardly-tapered metallic sections, comprised in the cylindrical body ofthe corelbar the sections A being arranged oppositeeach other, as arealso the sections B, and the sections B being in terpcsed between thesections A andvicc verse. v I G is a. central stem arranged within thecylindrical body, and having, an aperture (1 and equipped with collars bb"; the said collars b 6' being fixed to the stem by set screws 6, orother means compatible with the purpose of myinvention."

The couplings J are designed to be engaged by the hook-shaped arms ofvertically swinging levers Q, the other arms of'sai levers beingcomparatively heavy. The levers Q, are fulcrumed on links at the lowerends of chainsR, and the said chains Rare conneted, in turn, to a ringS. This ring S is designed to be connected to a cable (not shown), foruse in lowering the core bar and in raising the same from a flask; Alsoconnected to the ring S is a chain T which. is connected in turn to aclevis U, a portion of which is disposed in the aperture a of the stemC. A bar V disposed in comparatively long links a of the chains R, isextended signed to be moved vertically by the said 7 upward heads of therods J J acting against chains R can with the aid of the the stem by thechains R,as herev It will be notice 6 however,'at this point thatbecause of the disposition of the bar V in the long links w, the bemoved upwardly to a limit ed extent independently of the bar V and thechain T;

In the practical use of my improvements, the core bar or print is placedin a flask chain T, and also inafter described.

0, and at any suitable time precedent to the withdrawal of the bar orprint, thefhooks of the levers Q are engaged with the couplings J 7 Whenit is'desired to remove'or withdraw the core bar or print, upward'pullis exupward pull will first raise the couplings J 5 and thereby draw thearms or latches G upwardly and inwardly. Subsequently tothe saidmovement of the arms or latches G, the continued ull on the ,couplings Jwill, by the bars dTti acting against the raise the collars E and ,J soas to raise and draw inwardly the body sections 'A.- The upward movementof the reason 0 collar J will press the latches I inwardlyso :as toenable the sleeve H to clear the heads of said latches, and "then thecollarsE and the upper flanges of the 1 sleeves D and H, respectively,will move the said sleevesD and .H upwardly, and release all parts so asto enable the body,sec tions B to move downwardly. and contribute to thereduction of the core bar or print in diameter 50 that the same can bereadily withdrawn.

- '1 have enteredf nt'o detailed description 1 chain '1 connected withof the construction and relative arrangement of the parts embraced inthe present and preferredembodiment of my invention in order to impart afull, clear, and exact understanding of the said embodiment. I do notdesire, however, to be understood as confining myself to the saidspecific construction and relative arrangement of parts, as, in thefuture practice of the invention, such changes or modifications may bemade as fairly fall within the scope of my appended claims.

Having-described my invention, what I claim and desire to securebyLetters-Patent, is:

1. The combination with a body having opposite downwardly-taperedsections and opposite upwardly -tapered sections, one pair of sectionsbeing movable with respect to the other, of a stem disposed within thegroup of body sections, movable latches carried by said stem andarranged to hold one pair of body sections against movement, collarsmovable on the stem in the direction of the length thereof and connectedwith 'sai pair of sections, means for moving the latches and the collarsin the order named, and means connecting the other pair of body sectionswith the stem.

2. The combination with a body comprising opposite downwardly-taperedsections and opposite upwardly tapered sections alternating with thedownwardly tapered sec-' tions, one pair of sections being movable withrespect to the other, of a stem disposed within the group of sections,sleeves movable carried thereby, said sleeves and upper flanges, and theupper sleeve having diametrically opposite slots registered with adiametrical slot in the stem, links connecting the lower flanges of thesleeves with opposite body sections,
